Mark Korven (Mark_Korven@goodmedia.com) gleaned the following quote from the book The Scandal Annual 1991.
"A Wall Street bond trader sued for return of a $32,000 down payment he made on a $650,000 Victorian mansion on the Hudson River in Nyack, New York. The Reason: he said nobody told him that three Revolutionary War ghosts haunted the dwelling. The owner of the house had refused to return the money, saying that the ghosts were very friendly. The judge ruled in her favor, stating that the law can't take supernatural entities into consideration."That ruling panicked lawmakers in neighboring Connecticut, which evidently has more than its share of spooks. Legislators pushed though a "Ghostbuster" bill, making it mandatory for all home seller to disclose any spiritual phenomena related to the property."
